A skydiver jumps from a plane. Assuming she is not slowed by air resistance, what is her speed after falling 10m? (Round g to 10m/s2).

14.14 m/s

Explanation:

We first use the following formulae to derive time t;

½ a * t² = x where;

x - distance

a - acceleration – 10m/s²

t – time

½ * 10  * t² = 10

t² = 10 / 5

t = 1.414 s

TO find final velocity;

V = a * t

V = 10 * 1.414

14.14 m/s
